Cornerback Marchez Coates of McDonough High School (Waldorf, Md.,) had a marvelous day at the Pittsburgh camp yesterday, showing off his change-of-direction speed, his 4.4 40-yard-dash time and his awesome cover skills. It was nothing new for Coates, who has earned numerous camp MVP awards this offseason. At all the previous combines, however, Coates left town without a scholarship offer, becoming perhaps the most perplexing recruit in Maryland. That changed on Friday.
